SlPHON-CLOSET FLUSHING AND REGULATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 376,090, dated January 10, 1888.

Application filed January 31, 1887. Renewed October 13, 1887.

To all whom it may concern.-

Be it known that I, PATRICK HARVEY, a citizenof the United States, residing at Chicago, in the county of Cook, and in the State of Illinois, have invented certain new and useful Improvements in Siphon-Closet Flushing and Regulating Devices, which are fully set forthin the following specification. r.

The purpose of this invention is to provide improved means for furnishing flushing-water to the closets which are evacuated by means of asiphonic discharge-duct,commonly known as siphon closets, and to regulate the amount of exhaust force produced for the purpose of exhausting the air from between the traps in order to bring the siphon into operation and to regulate the amount of afterwash.

In the drawings, Figure 1 is a vertical sec tion of a flushing -regulating device which constitutes my invention, andis located in the service-box of the supply-tank. Fig. 2 is a horizontal section at X Xin Fig. 1. Fig. 3 is a vertical section of a siphon-closet bowl and traps, such as designed to be operated by my device.

A is the bowl; B and B,two traps in the siphonic evacuating-duct. between the twotraps. G is the tank. O is the service-box. D is the flushing-pipe; E, the air-pipe which communicates with the air-space B of the closet and also with the flushing-pipe.

As illustrated, and preferably, the upper terminals of the flushing-pipe and the airpipe are formed integrally in a single fitting which is inserted through the bottom of the service-box and protrudes thereinto. The flushing-pipe, therefore, may be said to protrude upward into the service-box, the portion D being above the bottom of the servicebox; and,as illustrated in the drawings, the airpipe E also protrudes up into the servicebox and enters the flushing-pipe in the portion D thereof. The part B of the flushingpipe has the lateral ports d located at the lower part of said portion D, and therefore near the interior of the bottom of the service-box. Said portion D of the flushing-pipe is preferably expanded above said ports, and into said expanded portion D the air-pipe E enters laterally. The flushing-pipe is entirely opened B is the air space I Serial No. 252.228. (No model.)

at the upper end, except as it is closed by the thimble or sleeve F, which is in effect a hollow turn-cock entirely open downward, and having also the lateral ports f, which, when said sleeve F is inserted within the portion D of the flushing-pipe, as illustrated in the drawings, registers longitudinally with the ports dof said flushing-pipe. Said sleeve F has also above the ports f lateral ports f which register longitudinally with the expanded portion D of the flushing-pipe extension D. From the wall of said sleeve longitudinally between the portsf andf there is thrown out interiorly the flange F, which projects downward and inward, forming a conical or funnel-shaped annulus within the.

said-sleeve and within the circle in which are located the ports d and f. Through the upper end or head of the sleeve F is an opening into which is screwed the pipe G, for the purpose hereinafter explained.

The operation of this device is as follows: 'When by any means the valve H, which controls communication between the tank and the service-box, is opened to admit water to the service-box, the same flows out through the ports dandf into the flushing-pipe, and continues thus to flow, constituting a forewash to the closet,'until the water rises abovethe mouth of the pipe G and cuts off the air from the air-pipe E. Thereafter the water flowing through the portsf, discharging against the funnel F, forms a sheet of Water around the mouth of said annulus and operates in a fa miliar manner to draw the air through said annulus, thus exhausting it from the. pipe E and from the airspace B between the traps of the siphonic evactuating-duct of the closet. This process continues until the valve H, having been closed and the supply of Water to the service-box. thereby cut off, the water again falls below the level of the induction-mouth of the pipe G, whereby the air is again admit- 5 ted through said pipe byway of portsf of the sleeve F into the air-pipe E. The siphon is broken by the admission of air thus to the air-space B, and the water in the service-box, which subsequently passes out throughthe ports f and d, constitutes anafterwash for the closet, and primes the traps in a familiar manner and for the usual purpose. The amount of this afterwash is determined by the depth of the water in the service-box below the induction-mouth of the pipe G, since the height of that mouth determines the point at which the air begins to enter the air-pipe, and by making said pipe G adjustable vertically at its connection with the sleeve F, as by threading it through the same, as illustrated, I provide for varying the amount of the afterwash according to thecapacityof the traps and other circumstances affectin g the quantity desired.

The degree of vacuum produced in the airspace B-that is to say, the amount of air withdrawn therefrom in producing this siphonic action-will depend chiefly upon the amount of water discharged around the mouth of the air-pipe within the fiushing-pipethat is to say, around the funnel F. I provide for LII regulating this discharge by adapting said sleeve F to turn within the portion d of the flushing-pipe, so that the portsf may coincide with the ports 11 to a greater or less extent, thereby admitting greater or less quantity of water from the service-box into the flushing-pipe.

It will be observed that after the water rises above the induction-mouth of the pipe G it might flow outward toward the closet through the air-pipe E, as well as through the flushing-pipe D; but by making an aperture on the pipe G less than the aperture through the funnel F this result is prevented, because the water that enters through G falls immediately through the annulus F and through the flushing-pipe D, so that this water co-opcrates with the water discharged through the ports f outside the funnel in drawing the air from the pipe E.

If in any case the upper communication, G, becomes stopped, there will still be a forewash and afterwash made up of the quantity of water below the lower point of the funnel F, and said funnel may be so looked that all necessary fore and after wash may be afforded in that way, and the said funnel and the said sleeve to which it is attached may be made vertically adjustable to vary the amount of the fore and after wash.

The screws F set through the top flanges of the sleeve F against the top of the flushing-pipe, may effect such adjustment.

I claim- 1. In combination with the flushingpipe having water-induction ports and the air-pipe communicating with the flushing-pipe above such ports, the sleeve F, concentric with the flushing-pipe and having ports corresponding in position with its said water-induction ports, said sleeve being rotatable with respect to the flushing-pipe to vary the extent of the coincidence of said ports with the water-induction ports of the flushing-pipe, substantially as and for the purpose set forth.

2. In combination with the flushing-pipe having water-induction ports, the air-pipe communicating with the flushing-pipe above said ports, and the funnel F within the flushing-pipe commencing between the air-pipe communication and the water-induction ports and extending down into the belt or zone of said ports, substantially as set forth.
